9yd x 3ft/1yd x $2/ft = $54/ft
9yd x 3ft/1yd x $2/ft = $54/ft

9yd x 3ft/1yd x $2/ft
Ignore the numbers, just look at the units:
yd * ft/yd * $/ft
The yd in the numerator cancels the yd in the denominator. Similarly, the ft in the numerator cancels the ft in the denominator. There is only $ left. So, your $54/ft should just be $54.
